So what is LASER i3?
“LASER i3” refers to a study conducted by evaluators from the Center for Research in Educational Policy (CREP) at the University of Memphis on student performance at schools implementing the LASER model (Fig. 1). Over three years CREP studied approximately 60,000 students and assessed the impact of the SSEC’s products and services on a subsample of more than 9,000 elementary and middle school students in (1) the Houston Independent School District (HISD), (2) eight school districts in northern New Mexico, and (3) seven school districts in North Carolina. They found that the inquiry-based science promoted by the LASER model improved achievement not only in science, but also in reading and math. LASER plays a critical role in bolstering student learning, especially among underserved populations including children who are economically disadvantaged, require special education, or are English language learners.

How did teacher practice change as a result of LASER?
Participating LASER teachers at grades 1–8 received a Science and Technology Concepts (STC™) unit each year for three years. This curriculum was accompanied by another integral part of the LASER model: professional development (PD). Teachers received two trainings in each unit to practice pedagogical strategies and gain deeper content knowledge for successful implementation. LASER teachers found these ongoing PD opportunities useful to improve their own knowledge and skills as well as preparing them to implement the curriculum. In 2014, evaluators asked teachers, “How useful to your science instruction was the professional development you received last year?” Of LASER teachers receiving the SSEC’s PD, 67.6% found it “very useful” while only 23.1 % of teachers in the comparison group said the same of their school district’s PD.

What does the future hold for LASER i3?
The LASER i3 study demonstrates that inquiry science improves student achievement not only in science but also in reading and math for students of all abilities at elementary and middle school. We know inquiry science programs supported by the LASER model play a critical role in bolstering student learning in science, reading, and math among all students and especially among English language learners, the economically disadvantaged, and students receiving special education. Students are learning science and loving it, thanks to the legacy of LASER i3 and the LASER model’s five elements: a research based-inquiry-centered curriculum; differentiated professional development; administrative and community support; materials support; and state and local assessments to measure the impact on student learning. Armed with this validation, the SSEC will continue its efforts to transform science education and support the LASER i3 regions as they sustain and scale the great work that has already been done.
